If the projector does not turn on when you press the power button or it turns
off unexpectedly, try the following solutions:

working electrical outlet.
• The projector's buttons may be locked for security. Unlock the buttons in
the Control Panel Lock setting in the projector's Settings menu or use the
remote control to turn on the projector.

mode after a period of inactivity. Perform any operation to wake the
projector. To turn off sleep mode, select Off as the Sleep Mode setting in
the projector's
ECO

• If the projector's lamp turns off unexpectedly, the A/V mute timer may be
enabled. To turn off the A/V mute timer, select Off as the A/V Mute Timer

enabled. To turn off the lens cover timer, select Off as the Lens Cover

• If the projector's lamp turns off, the status indicator is flashing, and the
temp (temperature) indicator is lit, the projector has overheated and turned

check its batteries and make sure at least one of the remote receivers are
available in the

settings. Also, when the projector wakes from standby status, the fans may
cause an unexpected noise. This is not a malfunction.

Solutions to Problems with the Remote Control
If the projector does not respond to remote control commands, try the
following solutions:
• Check that the remote control batteries are installed correctly and have
power. If necessary, replace the batteries.
• Make sure you are operating the remote control within the reception angle
and range of the projector.
• Make sure the projector is not warming up or shutting down.
• Check to see if a button on the remote control is stuck down, causing it to
enter sleep mode. Release the button to wake the remote control up.
• Strong fluorescent lighting, direct sunlight, or infrared device signals may be
interfering with the projector's remote receivers. Dim the lights or move the
projector away from the sun or interfering equipment.
• Make sure at least one of the remote receivers are available in the Remote
Receiver
setting in the projector's
Settings
menu.
• If the
Remote Receiver
setting is disabled, hold down the [Menu] button on
the remote control for at least 15 seconds to reset the setting to its default.
